will enable others skilled in the art to which it appertains to make anduse the same.

My present invention pertains to im- :.provements in windshields formotor vehi-' cles, the construction and advantages of which will hehereinafter set forth.

Windshields of various types have heretofore been proposed and used withgreater or less success, but it is a well-known and recognized lfactthat in rainy or snowy weather the operators vision through the wetglass is materially impaired and it becomes essential. toswing the glassand its supporting frame outwardly to obtain an unobstructed view. Theswinging of the glass,in order to obtain a proper and clear range ofvision, necessarily produces a wide opening directly into the car, withthe consequence that the rain and snow will drive in so that under suchconditions the shield is of questionable value. j The prescnt inventionhas for its object the production of a shieldlwhich obviates thesedifliculties and objections and which, while providing a clear line orfield of vision, effects the same with a minimum amount of opening orseparation between the contiguous edges of the shield.

A still further object resides in the special placement or angulararrangement :of the shield elements, so as to preclude, to a greater orless extent, the formation of eddies or currents whiclnwould otherwisehave the effect of passing directly through the opening, carrying therain or snow therewith.

A. still further object of the invention resides in the {means employedfor raising and lowering tlicmovable glass or plate, which means may bereadily operated from within the car, and which will be automaticallylocked "in its adjusted position.

One embodiment of the invention is shown in the annexed drawings,wherein:

Figure l is'a longitudinal sectional view,

taken on the line I -ll of Eig.\ 2, looking" from the interior of thecar;

Fig. 2 a transverse vertical sect1onalview,'

taken on the line II II of Fig. 1;

Fig. 3 a horizontal sectional view, taken on the line III-III of Fig. 1;

Fig. & a detail View of a portion of the actuating mechanism for raisingand lowerin?i the movable element of'the windshield; an r 5 a detailperspective view of the movable element of the shield and one of theracks carried thereby.

In the drawings 1 denotes a portion of the body of an automobile ormotor-car, and

2 the top thereof, a cross-rail 3 underlying the top at the forwardportion of the body 1. Said rail is provided with a recess 41,'extending from the under face upwardly and inclining rearwardly towardits upper side or edge.

Secured at each end of the cross-rail. 3. to the frame or body 1 and-toa lower cross rail 5, is a side frame 6, triangular in outline andcarrying a pane or window 'Z 7 Closing the space between the two sideframes 6 1s a fixed pane or plate 9, of glass which, as will be seenupon reference to. F 1g. 2, inclines outwardly toward 1ts.upper. end andterminates short of the Junction.

between the two forward members 9 and 10 of the frame (5. The members 10of said frame are recessed orfgroovcd in their oppo sitely-disposedfaces;"to receive the sliding plate 11 of the windshield. Said plate-isprovided with metalzllindings l2 along-the tion of each of sa'id'bindings is sccured'a rack 13. The grooves in the members 1' 10'vertical edges thcre6f, and to the upper pore binding and rack may bemoved upwardly into the same when the plate 11 is el'cva'ied When theparts are in their closed ,-posfition,- the lower edge of the plate 11passes beyond and overlaps the upper edge 01 the plate 8, as shown inFig. 2.

T o eifcct the raising and lowering offhe plate 11. any suitablemechanism ma v; he employed. but i prefer to utilize thatshon'n herein.Secured to the. cross-rail 3 is a mix of hangers 1d,,i'n which is'journalcd a shaft 15, carrying .at each end a pinion 16, which pinionsmesh with the respective racks l? 35 with the minimum plates 45 the.swinging body, a windshield located at at. end thereof, said shieldhaving an upper BEST AVAYLABLE ooP at each end of the plate ll. Theshaft 15 passes through a box or housing 17. held. against movement by astrap or hanger 18, secured to and extending downwardly from 5 thecross-rail 3-.

Shaft 15 also carries a worm-wheel 19, which is in mesh with a worm 20,secured upon a stub-shaft 21, mounted in suitable hearings in the box orcasing 17. The shaft 21 extends outwardly into the car for a shortdistance, and a hand-wheel or knob 22 is secured thereto, through themanipulation of which the occupant of the ca r may raise and lower themovable plate 11. As will be readily appreciated, by turning the knob ofwheel 22, motion will be imparted to the shaft 15,

through the worm and worm-wheel, and pin-v ions 10 meshing with theracks 13 will raise or lower the plate 11, and this without any bindingor cramping of the plate in its 80 is in its lowered position.

By moving the plate 11 in a right line, instead of swingin the loweredge of-the same outwardly aiout a pivot located at or adjacent itsupper amount of movement of the plate and with, consequently, theminimum opening between the edges of the 8 and 11.to obtain a clear lineof vision. whereas, with a swinging plate, one

to necessarily has to move it through a considerable are before theproper clearance can be obtained. The swinging movement, therefore,necessitates a relatively wide opening or space between the lower edgeof plate and the contiguous fixed element, with the consequence that therain and snow will beatinwardly through such Side o 'iening.

- With the present structure, having fixed so and movable elementsarranged in relation to each other as herein shown, and the movableelen'ient bodily tttlJllStfllJlO in a right:

, L linc. or in the plane of its disposition, I find xthat a clearvision may be obtained with a minimum amount of opening or clearancebetwcei'i the fixed and movable elements, and lhat'the aii currents setup do not carry the rain inwardly through the opening, but on the=.':oiit.rai.'y, they tend to cause it to swirl an away from suchopening.

.lla ring thus described my invention, what- I claim is:

1. In combination with a motor vehicle the forward portion, I amenabled,

' in combination, two panes, said member inclining forwardly toward itslower edge and serving, by reason of such inclination, to cause theimpinging air to pass away from the lower edge of sald member; and meansfor bodily raising and lowering said member in line with its plane ofangular disposition.

2. In combination with a motor vehicle, a wind-shield therefor,comprising an upper member inclining forwardly toward its lower edge,means for bodily raising and lowering said member in line with its planeof angular disposition, and a fixed member located below the uppermember said fixed member inclining forwardly toward its upper edge.

' 3. In combination with a motor vehicle, a wind-shield therefor,comprising an upper member inclining forwardly toward it's lower edge,means for bodily raising and lowering said member inline with its planeof angular disposition, and'a fixed member located below the uppermember, said fixed member inclining forwardly toward its upper edge,which edge under-lies the upper member when the latter is in its closedposition[ 4. A windshield for vehicles, comprising, in combination, per,movable pane, the lower edge whereof, when the parts are closed,overlaps the lower pane; and means for raising said movable pane bodilyin its plane of disposition.

5.
